mized as much as possible. This tilting is a yie d suflicient ness of the sliver and wit out undue tilting.

Itis a-further object of my invention to so for the support well-known fault, and my endeavor in thepresent invention has been accordingly to so ap ly the weights that theup er rolls will y when re uired y the thick aplply the weights or by such means that the ros may bereleased to be taken out without lifting the weights orseparating them fromv the machine, :and upon replacing the rolls they may be subjected to the retainin action of the weights with as little troub e as possible.

, There arealso embodied in my invention various other incidentaltim rovements, all .of which will be explained y reference to the drawings, in which I have shown enough of a machine to make my invention understandable. l

Figure'l is a vertical section of a portion of .a drawing-frame. embodying my invention with the cover open, Fig. 2 being a portion of a lan view; Fig. 3, a vertical section of the ro l-supports, taken on line 3 3 of Fig. 2 with the cover closed; and Fig. 4, a detail taken in front elevation;

Ais the bed, whichmaybe supported in the usual way and carriessupports A. There are a number of these supports, although two only are shown, and onwhich is mounted a stand B, carryingfa number of .blocks b, b, 6?, and b? for the sup ort of the rolls 0 and 0, arranged in. pairs, .representing the lower rolls andC the upper rolls. Theblocks .act

bearing with respect to the lower ro s.

these pairs of rollsin thev while the journals 0' of the upper rolls C are preferably mounted to turn in boxes or bearings c squared to fit into the recesses in the blocks and in which recesses also the boxes are vertically movable or adjustable, thereby .providingfor the vertical movement or yieldlng adjustment of the up er rolls. As shown, each block and recess is ong enough to carry also the adjacent journals of another pair of rolls, the second pair, however, being omitted in the drawings. The blocks also, with the exception of the first set, are mounted upon their stand to be horizontally adjustable thereon in order that the rolls may be adjustably separated from one another, according as the length of staple which they work upon The usual manner of locking them to the stand to permit of such adjustment is employed.

The rolls are shown constructed in the usual manner. They are fluted along their working portions, the fluted portions of each of the upper rolls 0 meshing with its lower roll 0. My invention is more especially concerned with the means for yieldingly holding down the upper rolls in-their proper lace nd or this purpose there are shown cross-bars D, the ends of each of which rest upon the blocks b 6 respectively, each cross-barlying above the journals and boxes of the upper rolls 0 and closing the entrance to the recesses in which said journals and boxes are contained. These cross-bars are held in lace by weights E E, applied at their ends t ough connecting or coupling rods E E These couplingrods bearing the weights connect with the ends of the cross-bar in the following manner: In the bed of the machine are formed holes tica holes 6 6, respectively, in the blocks 1; 6 on which the ends of the cross-bar are resting. The 0011 ling-rods are assed through these holes, t e coupling-r0 E passing throu h the holes a and e and the couplin rod 3 through-the holes or openings at an e. In

connection with the passage of the couplingrod E through the bed of the machine it is to be noted that the hole or opening a, therein is made elongated or slotted, so that the coupe ling-rod may travel therein and not interfere with the adjustment of the block I), through which it is passed or openings at a, which register with the ver- Above the block b the upper end of the coupling-rod E is bent over to form an eye e while the upper end of the coupling-rod E passed through the block N, is turned over to form an arm 6 Each end of the cross-bar D is made cleft or forked, the prongs d of which at one end receive between them the eye 6 on the end of the coupling-rod E and a hinge jointure is then made by a pin d, passed transversely through the prongs and through the eye 6 of the coupling-rod between them. On the other end of the cross bar the prongs d are made sufficiently wide apart to receive between them the upper end portion 6 of the coupling-rod E which, as maybe noted in Fig. 4, is enlarged at this point to form a shoulder 6 bearing against the top of the block 6 by which means the rod and attached weight are supported. This portion 6 of the rod above the shoulder e and between it and the bent arm (2 is of a length or extension substantially the vertical thickness of the cross-bar D, so that with the end of the arm resting upon the block in normal position the arm a on the end of the rod may be turned around to lie over the one or .the other of the prongs (1 by which means the end of the cross-bar is jointed or locked to the coupling-rod t with a yielding ointure and without the necessity of lifting the coupling-rod and attached weight. Instead of making the portion 6 of the rod enlarged to form the supporting-shoulder e the rod, as shown in Fig. 3, may have at this point an auxiliary sleeve 6, one end of the sleeve forming said shoulder and the other end bearing against the arm a as a stop. Of course any other mechanical expedient ma be resorted to to form this shoulder; but I prefer one or the other of the above means as being the most practicable.

In order to prevent the bars D from being accidentally unlocked, I prefer to provide a cover F, hinged to the upright F and having at its front end ribs j, which straddle the arms 6 of the rod E when in position looking the cross-bar. (See Fig. 3.)

It will be seen that the cross-bar and attached weights at one end of the rolls are duplicated at the other ends, and with the parts thus constructed and combined when the rolls and cross-bars are in normal position the cross-bars will rest on top of the blocks 1) and b just clearing the journals, or rather the journal-boxes, of the upper rolls and be held in place at either end by the attached weights, the attachment being such that one end of the bar will be provided with a yielding hinge and the other end with a yieldin lock, so that the parts may properly yiel when required by the thickness of the sliver. Thus normally no stress will be exerted to press down the upper rolls upon the lower rolls. The pressure of the weights is nor-' mally received by the shoulder a and not by the cross-bar D. When, however, there is any tendency on the part of one or more of the u er rolls to rise unduly, it or they will be held down by the combination of both weights E E, acting on the cross-bar D, or by one of the weights, the opposite end of the cross-bar yielding or turning upon the pin (1 or the arm 6 as upon a hinge. A sin le weight may therefore control an one o a number of rolls or all of them. t is also to be noted that the cross-bar will act as a lever to apply weight in a more efficient way than by direct action. The effect is that the upper rolls will be more evenly maintained. There will be less opportunity for the rolls to tilt, any undue tendency in this particular, whether on the part of one or more rolls, being immediately corrected. After the cover F is turned back the cross-bars may be removed and the rolls taken out simply by turning the arm 6 into alinement with the slot in the end of the cross-bar. The crossbar can then be turned back upon the pin d as a hinge, (see dotted hnes of Fig. 1,) when the rolls can be taken out, and this, moreover, without the necessity of lifting the weights. After the rolls are replaced the cross-bars can be turned down and locked simply by turnin the arm a of the coupling rod over one or the other of the prongs d on the end of the cross-bar. This operation also can be accomplished without the necessity of lifting the weights, at least when the crossbars are in normal position resting upon their blocks, for, as before explained, the coupling rods E are sup orted by their shoulders 6 contacting witli the blocks in such manner that their locking-arms 6 may be turned over one or the other of the prongs d without the necessity of lifting the weights. If there is sliver between the rolls sufiicient to raise the locking ends of the cross-bars from their blocks, then it may be necessary to raise the weights slightly for the lockingarms to make their engagement; but this can be accomplished with very little trouble. Another benefit derived from the means shown of locking the ends of the cross-bars resides in the fact that it permits of the blocks and rolls being adjusted in their position, as before explained, for the slot in the locking end of the cross-bars is made sufficiently long to permit of their being adjusted some considerable amount and still receive the ends of the coupling-rods E and the engagement of the locking-arms.

While I have shown my improved construction as applied to four pairs of rolls, it is evident that the number of pairs of rolls may be increased or decreased as desired, as, in fact, other structural arts of the machine may be varied without eparting from the spirit of my invention What I clairnas my'invention is 1.
